DAVID J. cAIN, or cAscADA, IDAHO -FLDING CHAIR Application jaleaseptember This invention relates tochairs, and more particularlychairsof the folding type, the primary object of the invention being toprovide achair of this character which .may be compact article, dueconsideration given to the strength and durability of the cha1r.`

chair in their folded positions to insure against the legs swingingoutwardlyv when the chair is being moved from place to place. A furtherobject o-f the invention is the provision of means to lock the legs intheir eX- tended or active'positions to insure against the legs foldingwhile aperson is seated on the chair. A

With the foregoing and other'objects in view which will appear as thedescription proceeds, the invention resides in the combination and'arrangement of parts and in the details of-con'struction hereinafterdescribed and claimed, it being understood vthat changes in the preciseembodiment of the invention herein disclosed, may be made ,Withinthescope of what is claimed, without departing from the spirit oftheinvention.

Referring to the drawings: -v Figure 1 is a vertical sectional Viewthrough a chair constructed in accordance with the invention'.

Figure 2 is a front elevational view thereof. Figure 3- is a fragmentalsectional view illustrating the back latching mechanism.`

' Figure 4 is a bottom plan view illustrating the legs in their extendedpositions. I

Figure 5 is a bottom plan view illustrating the legs of the chair intheir folded positions. Figure '6 is a` .transverse lsectional Viewthrough the chairthe back and leg sections being in 'their foldedpositions.

Figure? is an enlarged fragmental view` iliustrating the connectionsbetween the back and seat. l

Referring to the drawings in detail, the reference character 5designates the bottom or seat portion of the chair to which the backsecuring plates 6 are fastened, theback securing plates embodying spacedflanges be- 1 I for latching the back -An important object of the'invention is to vprovide. means for lockingthe legs of'the e4, 192e.

. which lpivotally mounted.

Oneflange'of each fastening plate is provided with spafced openingsdesigned to rerods 8 that constitute the latching mechanism in eitheritsactive or inactive position. As shown, the inner ends of the rods '8are extended; at right angles defining linger pieces 9 that extendbeyond the transversel bar 10 of the back so that they may be readilygripped by the operator .to move the rods 8 outof engagement with thewalls of the openings in the flanges of the pla tes 6.- In .order thatthe rods 8 will be lnormally urged laterally, a spring 11 is providedand has its lends contacting with the rods as shown by Figure 3. i

The legs of the chair are arranged in pairs, the front pair of legsbeing pivotally sup! l ported between the flanges 12 of the securing'vplates that are disposed adjacent to the front of the chair, whiletherear legs are pivotally supported between the anges 18 secured to:the -rear thereof.

the side .bars 7 of the back, are l the underside of the bottom of thevchair, atf

- Connected with each pairiof legs isa subl stantially U-shaped rod 14adapted to move into engagement with the keeper 15, secured to the undersurface of th'ebottom of the chair at a `point substantially centrallythereof, the keeper vbeing provided with a central rib 16 against whichthe rods engage to hold them against movementin one direction.

Forming a part of the keeper is a slidable latch 17 adapted to move overthe rods to hold themin their active positionswhen they have been movedto extend the legs of the chair.l "A stop 18 is disposed adjacent to thekeeper and restrictsmovement of the slid'able latch in one direction:

When'the legs `afereleased ,and moved to, their folded or inactivepositions, it is obvious that the legs' of one pair will fold over thelegs of the adjacentpair, and the rod of the overlyinglegs willengage-the rspring' latch 19 lwhere the ,leg members will be heldsecurely in'their folded positions.

From the foregoing it will be obvious that..

4 due to the construction shown and described,`

the legs ils Well as the back of the chair may be swung from theiractive to their inactive f posltions or vice versa, and securely held 1nsuch positions Withoutdanger of them fold- ?Ong'or swinging outwardly,as the case may I claim: f

In a foldablechair, a seat portion, pairs of leg members pivotal'vlylconnected With the Seat portion, U-shaped rods connected With the letgrmembers, a keeper secured to the underside of the seat portion andincluding a i rib, said .rods adapted .to engage opposite sides of therib to restrict movement of the rods, and a/.slidable member associatedwith i the rods Within the keeper.
